"In the course of my readings and research concerning the life and work of Jean-Jacques Rousseau, I was induced to collect postcards on the subject. Little by little, I developed the idea of writing a pictorial biography of this great writer and philosopher of the 18th century. I wanted to present the public with a well-reasoned account of his life and work. This brief biography illustrates an extraordinary destiny. For more than two centuries, Rousseau has aroused constant and vivid interest. He leaves nobody indifferent."
